17 Claims.

If-he present invention relates to an inserting machine, andi particularly` an inserting machine forum-stalling armature conductors into an armature.

ftis an obiect 'of-the invention to provide an apparatus of' this kindy which will automatically feed, cut and inserta series of armature conductors-lof propernumber'into various peripheralilly spaced slots in an arma-ture.

More particularly, it is `anobiect of the invention to provide a mechanism of this kind having a feed, a cutting means and an armature 4holder with interrelated operating means for the three-elements; so' that the feed supplies the proper amount of `wire and rod at the proper time ith-rough the cutting means, while the armature holding means disposes a proper slot for insertion 4of the end "of the wire into the slot, and at the proper time the cutting means cuts off the rod, whereafter the cutting means withdraws the :armature holding means, shifts to presenta new slot,. anda new feed cycle may begin.

A furthervobject is to .provide-.means for causing the mechanism to operate to ll all of the slots of :a given armature and thereafter to stop.

vA further object is. to provide a mechanismof this hind that-may be operated from the familiar :press head type of machine.

A `further object is to provide `an adjustable machine vthatmaybe usedl with different sizes of armatures and different numbers of conductors.

A further object is the provi-sionY ofY a lcutting means that isI operable by a rotating member to .effecticutting only byvrotationi in one direction.

Fig. lil is a view partly in section of one ofthe cutter links;

Fig- 12 is a `section through thecutter link, taken on the line I.2-Il2 of Fig. 4;y

Fig. 13 is a plan view of the presserplate` or ram adapter; and Y Fig. 14 .is adiagrammatic view of the operating'parts ofthe machine.

The apparatus is conventionally mounted upon a base 2li that may be the bed of a press machine which has avertically reciprocating head 2l, preferably reciprocated up and down by a motor, shown .at M in Fig. 14, through conventional drivingmeans, as will be described in outline hereafter.

On the bed is mounted a feed means l22 at the left in Figs. 1v and 2, a cutting meansl 23 at the middle, -and an armature holding and rotating Imeans `24 at the right.

The feed means 22 is adapted to receive a wire Vor rod W from a suitable source of supply., such as a coil'. The wire is conducted through*y passages in itwosupports 25V and 26. Pairs `of feeding wheels 2l and 1281 are disposed between the two

supports

25 and 26, and additional pairs` 2'9' and 30 are disposed tothe right or inwardly fromfthe supportZd The feed wheels 2l and 29 are driven together through gearing 3I, 32, 33 in` conventional` fashion. These gears and their shafts. are supported on a vertical wall 3d extending upwardiy from `the base. o i

The `shaft 35', with the` gear 3l, is operated through a conventional' ratchet Yclutch mechanism so -that the gears `:M -33 are driven ina forward directionr but not in a reverse direction. v A driving mechanism, including gearing ."s'il and `38, operates the driving part of the clutch 36. `By this drive, as will; appear, `a series of intermittent one-way feed movements are imparted to the

lfeed wheels

27 and 29. The drive is operated from the operating motor M for the whole machine. This appears diagrammatically in Fig. 14, and' will' be describedhereafter.

rThe `wire passes kfrom the feeding means throughK atsupport l0 into the cutting means 23. This cutting means has a base W5 secured to the bed 2U of the machine. The base 45 has an upstanding wall- 46 thereon extending transversely `of the bed'. vIt also has a second 'wall or post 41, spaced axial-ly from the wall 46k As will appear,

3 the post 41 is axiaiiy detached from the wail 45 for the interposition of a rack member.

The wall 46 has a two-sized passage 50 therethrough to receive a drive wheel having a shape complementary with that of the opening 56, so that the wheel 5| is supported against end thrusts in one direction. The wheel 5|, in turn, receives a sleeve 52 inserted along its axis. The sleeve 52 has a head through which extends atta-ching means 53 (Fig. 3) for holding the sleeve within the wheel 5|. jection 54'extending to the right of the right face of the gear 5|, for purposes to be described. The sleeve has an axial opening therethrough whichis disposed in a line with the opening of th'e wire support 40.

The left end of the wheel 5| projects beyond the wall '46 and is toothed at 55 to mesh with corresponding teeth on a rack 56, which is interposed between the wall 46 and the post 41 (Fig. 1), the space between these members being of T-shape in cross section, to form a track for th'e rack.

The rack 56 is vertically reciprocable within the foregoing space, and is contained therein by a back plate 58 that spans the space between the wall and the post 41. This rack is attached at its upper end to a presser plate or ram adapter 60 secured to the presser head 2|. Thus the rack 56 will be reciprocated vertically in cycle and, as a consequence, the driving wheel 5| will be oscillated correspondingly.

The righ't hand face of the drive wheel 5| has two

opposite studs

62 and 63 projecting therefrom (Figs. 4, 6 and 12). The stud 62 receives one end of a link 64, and the stud 63 receives one end of a link 65. The links are complementary, and the link 64 is shown in Figs. 11 and 12. There it will be seen how the stud 62 is fastened into the face of the wheel 5|. The link 64 pivots freely about the stud, and at its free end has another stud 66 receiving a cutter wheel 61. Similarly the link has a stud 68 that carries a cutter wheel 69. The cutters are tapered outwardly to provide a shearing edge properly disposed relative to the machine parts yet to be described.

Each link also carries a spring pressed plunger 10, the design of which is clear from Fig l1.

These plungers are designed to spread the two links, as will appear, by an operation urging them to pivot about the

studs

62 and 63.

It will be seen th'at the two cutters 61 and 69 have cylindrical portions 12 and 13, respectively. These cylindrical portions are adapted to be engaged by a cam member on a cam ring 15. This cam member is circular on its outside surface, and is held in position by a retaining ring 16, there being suitable bolts 11 passing through the ring 16 and the wall 46 for holding these parts together. The retaining ring has an inwardly extending flange 18 that extends over the face of the cam ring 15. The cam ring may rotate within the confined space thus provided for holding it.

The cam ring 15 has an inwardly extending edge providing four

cam surfaces

80, 8|, 82 and 83, successively joined by radial edges. These cam surfaces are adapted to engage the cylindrical parts 12 and 13 of the two cutters 61 and 69, which latter are constantly urged into engagement with the cam edges by the plungers 10. In oth'er words, the plungers 10 tend always to separate the cutters.

The cam ring is permitted to rotate in one direction only, through a one-way clutch comprising a series of tapering slots 85, each containing a ball 86. In Figs. 4 and 6, this arrangement per- The sleeve 52 has a smaller pro. n

4 mits the cam ring 15 to rotate clockwise with re-h spect to the retaining ring 16, but it prevents counterclockwise rotation.

From the foregoing, it will be seen that when the rack 56 descends, the driving wheel 5| will be rotated clockwise in Figs. 4 and 6. This will move th'e links 64 and 65 clockwise also. After their respective cutter wheels `are 'theningengagement with a radial edge uponthe cam ring 15, this ring will also be rotated clockwise, a movement that is permitted by the clutch balls 86. When, however, the rack 56 starts ascending, the driving Wheel 5| will rotate counterclockwise. This movement willdraw the studs 62 and 13 counterclockwise. Any substantial movement of the cam ring 15`wil1fbe prevented by the clutch' balls 86, so that the links will be moved relative to the cam edges Bil-"83. This engagement of the cylindrical portions 12 and 13 upon the cam edges, along which they roll, will force the cutter wheels inwardly to the position shown in Figs. 3 and 4, where their edges are in shearing relationship. As the end of the upward stroke of the rack 56l is reached, the cutters will drop back of the radial edges on the cam ring 15 under the influence of the plungers 10, where they will be separated so that new wire may be fed.

The armature holding means 24 includes runners provided on the bed 20 to track a silde 9| for movement transversely of the bed. A support 92 is secured in upstanding relation uponv the slide 9|. This support holds a cylinder 93 immovably, and this cylinder, in turn, has

bearings

94 and 95 to support a shaft 96. A screw 91 with a washer holds the shaft 96 against endwisemovement in one direction. A cap 98 encloses the cylinder tightly.

The other end of the shaft 92 has a shaft |00 threadedly attached thereto. To this shaft is keyed a spacer wheel lill, which is clamped between one face of the support 92 and a shoulder on the shaft |00. It is likewise keyed to the shaft for rotation therewith. Its feeding operations will be described hereafter.

Also keyed to the shaft |00,` but removable therefrom, is a double disc arrangement comprising two circular disc members |03 and |04. The member 04 is smaller than the member |03, for a purpose to be described. The outer end of the shaft |00 is threaded to receive a removable cap |05. An armature, shown in dotted lines at A, may be disposed over the shaft |00 upon removal of the cap |05, and retained thereon securely upon return of the cap and upon its being tightened into position.

The feed wheel |i| has ratchet teeth |08 about its edge. These are actuatedby the lfollowing ratchet mechanism. The operating plate 66 extends axially to overlie this wheel-IUI. It is provided with a notch |09 (Figs. 8, 13)` opening toward the front of the machine to receive a screw H0 that is threaded into a plunger urged upwardly by a spring 2. This plunger reciprocates within a confined space formed by a vertically disposed angle member I3, the back end of which extends down against the back edge of the slide 9|. This member is duly secured to the slide. A third side of the plunger space is formed by a vertically disposed wall member |64, and a fourth side is formed `by a plate H5, the several parts being Ytightly secured together to form the plunger container. A cover plate I6 is secured over the top of this container and is provided with an opening through which the screw ||0 may pass.

The bail i3d is drawnzforward, I bringing `with it .the .armature support=means 2'4 'which isrnountediupon `the slideH, and to .whichthe bail is attached. Then'thecap 'H35 isunscrewed from the shaft Silit, `and an armature A, `usually comprising a seriesioflamlnations, is insertedover thefshaft against the-face ofthe disc Wfl. The shaft 'lzll has `a key corresponding `to the key slotfinthe armature so that the armature is disposed =`in proper position, and is held against rotation :relative to the shaft. At the start, the key is in theftwelve oclockposition. Thefcaplll is `tlrereupon replaced rand `l tightened to `hold `the armaturelinfplace. v

The armature rotating mechanism 2A is then moved backwardly until its 'hits the `adjiustab'le stop screw illi. It will be seenfthatthe slot l' inthe plate |30 permitsrthescrew Mii to move into and out of the presser plate 6D, forthewithdrawal and replacement `of the armature rotating mechanism. l

The screw Me is adjusted to stop the rotating `mechanism at a proper point `"to dispose thewslot in `the nine oclockposition,-for lthe particular diameter of armature, in axialalignment with the sleeve 52. `At this time, the press head 2i, the plate El) and the rack are all up.

The clutch is then --engaged by Closingthe switch |48. This starts `rotation of the shafts 15| and |52, and, after about one cycle, with draws the pin M5 'from `the switch blade 1546, 'whereupon the switch closes. The switch M8 may then be released 'This causes the feed mechanism 22 to project a predeterminedlength of vwire which goesintosthe armature slot,-then alignedwith the sleeve 52, and projects onboth sides 1thereof. Thereduced diameter of thedisc |04 permitsthe wire Vto-extendout thereover the proper distance.

AsLthe hea`d"2i descends, carrying the: rack 56 downwardly, no cuttinguaction occurs because .the driving wheelfl, thelinkszid and E5, andthe cam ring S15 are all moved clockwise, in Figs. 4 .and.6. The feedstops at the timezthe plunger 2| reaches the bottommfwits stroke. rllhe very last part of this stroke causes :the :plate .i60 to strike the nut Hf'l' 'of the armature rotating ratchet `wheel mechanism,so that thenal part of .the stroke displaces .the ratchet dog |22 the distance of onetooth, or several teeth, depending uponthe angular distance between adjacent armatureslots. `Displacing the nut lil upwardly increases the distance of angular displacement.

As the plunger ascends, .the cam ring :15 is held against motion by its ball clutch, while the .driving `wheel 5i is rotated counterclockwise,

` nwhich drawsthe cylindrical parts 12 and i3V of the T byra connecting 4rod and "Ib links 64 and 65 along .the inwardly sloping cam edges, and-causes the .two links to close the cute (ter wheels-together to cutqoi the wirethus disposed in the armature slot. This cutting action occurs between the ends of the upstroke, and 4further upward travelrthereaftercauses the `'Cylindrical parts 12 and 'I3 of the two cutter wheels to drop over a cam edge and be freed from cutting position under the influence of the plungers 10. A slight overtravel beyond the said radial edges of the cam does not return them to closed position. Thereupon, at the final part of the upstroke, the plate 60 strikes the upper nut ||8 on the screw |||l of the armature rotating means to lift the same to its starting position, at the same time advancing the armature the proper distance to dispose a new slot in position to receive the subsequently inserted conductor. After a complete revolution of the wheel during which all of the armature slots will have been lled, the pin |45 Will open the switch |41, to open the clutch |49 and stop the mechanism.

It will be seen 'that overtravel of the cylindrical portions 12 and 13 of the two cutters relative to the cam ring 15 is inconsequential, because a sub sequent downstroke will rotate the two links backwardly until they strike the edges, which will then provide a starting position for the following upstroke.

The detent mechanism, comprising the wheel |32 and the spring pressed plunger |33, will re tain the armature rotating wheel |0| in the position to which it is moved by the positive action of the plate 6|) against one or the other of the two nuts and ||8. The force of the spring ||2 is insufficient to overcome the detent mechanism.

It will be understood that the conventional feed mechanism 22 may be adjusted to vary the length of wire fed -per stroke. Different diameters of armature, and different angular spacings of the slots, are accommodated as already described. Armatures of different axial thick ness may be used by substitution of different backing discs |03 and |04, these discs being readily removable. Diierent armature shaft sizes may be accommodated by different shaft extensions |00, these extensions being readily removable. In case the teeth of the spacer ywheel |0| do not correspond to the angular spacing of the slots, differently toothed spacer wheels may be readily installed.

The removability of the sleeve 52 enables the cutting mechanism to be adapted to various sizes of wire conductors. The cutter Wheels are readily accessible for servicing when the slide 9| is drawn forward.

The machine is easily synchronized, as the feed mechanism operates through a clutch so that it may be adjusted relative to the rotating means, and the cutters are easily synchronized by reaching in and rotating the cutters backwardly against the one-way clutch.
